We're dividing 66136 by 68 
We want to figure out the number of times 66136 can be divided by 68.

On to step 1:
If we divide 6 by 68, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 68

Let's proceed to step 2:
68 goes into 66 0 times with a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (1) of the dividend behind the 66 and repeat the process: 661 / 68

Moving on to step 3:
The number 68 fits into 661 9 times, leaving a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 612 from 661 to get 49.
Append the next digit (3) from the dividend to 49 and continue with: 493 / 68

On to step 4:
The number 68 fits into 493 7 times, leaving a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 476 from 493 and we're left with 17.
Include the next digit (6) from the dividend after 17, then repeat: 176 / 68

Advancing to step 5:
The number 68 fits into 176 2 times, leaving a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 972.0
The remainder is 40 after subtracting 136 from 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 6:
When dividing 400 by 68, we get 5 with a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 972.5
Subtracting 340 from 400 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 7:
600 divided by 68 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 972.58
If we take 544 away from 600, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Going ahead to step 8:
The number 68 fits into 560 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 972.588
Deduct 544 from 560 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 972.588 with a remainder of 0.0016.
